I'd like to point out that this strategy may cause the concept of object 
finalization useless. The same problem appears in java (see
an excellent article at The strategy 
may also lead to poor
performance when garbage collection starts.

A better approach (at least in some cases) would be to (incrementally) garbage 
collect an object immediately after it's no longer

Ideally, the programmer would have the ability to decide garbage collection 
strategy for each object (for example, by implementing
interface IncrementallyCollectable, the object would be garbage collected 
immediately after it's no longer needed). A smart compiler
could also optimize the code by choosing the most appropriate gc method for 
each object.
